Intellectual Development

Piaget studies and formulations regarding intellectual development of children focus on the growth of brain. According to the study, human brain fully develops only in late adolescence. Sometimes full development of brain may occur in early adulthood that is even after adolescence stage in case of males. Parents sometimes expect their children to behave or respond like adults but children cannot be little adults. They can only start thinking as an adult after reaching the age of 15.
